The MGC-50 and the MGC-100 are high performance, high capacity
Multipoint Control Units (MCU) which support up to 48 ports for the MGC-
50, and 96 ports for the MGC-100. They utilize a variable port bandwidth
ranging from 56 to 1920 Kbps.

The system meets International Telecommunication Union -
Telecommunication Standardization Sector, (ITU-T, formerly CCITT)
standards for multipoint multimedia bridging devices, and meets ETSI
standards for telecommunication products. The MGC-100 DC also meets the
NEBS Compliant Standard (when so ordered) for our clients based in the
United States.
The flexible architecture in the system is designed to accommodate users’
changing multipoint needs. This system utilizes a modular “universal slot”
platform that allows the formation of different configurations based on users’
individual port capacity and functionality requirements.
